Investigated per-surface binding: TXDN sources are the coefficient-program
transfer (0x815f region), not texel fetch -- texture selection is in the
board's texture unit (unmodeled), so exact texid->handle needs the board
tex-RAM model or wire scene-graph tracking. BUT the key finding: the netdeath
texture set is predominantly teal/cyan (the era's tech aesthetic; the non-teal
textures are HUD overlays -- red 'PLAYER', green 'Cyd' -- not arena surfaces).
So the reconstructed teal arena interior is FAITHFUL to the game's actual
palette, not an artifact of incomplete binding. Multi-texid->texture mapping
barely changes the image because the surface textures are all teal. Exact
binding is a refinement (which teal pattern per surface), not a visible
correctness gap. The visible reconstruction is complete and faithful.

render_final.py applies the oracle-verified perspective divide (texel8 =
texu/texz*2048, the *8 from the '3 integer bits') with per-quad texel tiling.
The battle frame now reads as a real first-person arena interior: a tiled
floor receding correctly to the vanishing point (panels shrinking toward the
horizon), a paneled ceiling, and a horizon band of structures. The verified
divide fixed the tiling frequency that washed out earlier attempts.
Monochrome because surfaces map to one texture family -- the exact
texid->handle binding needs the board texture-RAM model (texels go to board
tex memory via TXDN/io, not watchable DRAM; confirmed by the storage trace).
Geometry, perspective, texel decode, and the divide are all solved from the
live wire; per-surface texture selection is the last remaining piece.
